To Dare Dominion (1) - S1.E54

John Thunder informs the Centurions that his old sparring partner Claw is now working for Doc Terror as a cyborg. Meanwhile, Doc Terror succeeds in creating a dimensional neutron vortex in his base, Dominion. Energy from the vortex is detected by Skyvault, where Crystal determines that the laws of reality will soon collapse. With Terror having stealth and scrambler fields all over the Arctic to hide his base, the Centurions lure Hacker into stealing a vital component for the vortex, and John sneaks on board Terror's airship. John makes it to Dominion, where Claw soon senses his presence and alerts Terror, who then gets Hacker to attack the SETI space probe station in the Andes to keep the rest of the Centurions occupied. Claw captures John and attempts to settle old scores with him. The other Centurions are sent to locate Dominion, but are too late, as Terror's dimensional vortex breaks out of control.
